l Application lcd August Il, 1914. Serial No. 854,983.

To all 'whom it muy concern:

.Be it known that we, Manitu Sernac and Sirnrinn-i Sereno, subjects of the Emperor Austiia-lvliingary, residing at Clarence,

.u the wearer in a floating position for swimming' in the water.

A further object of this invention is the` jjnovision ot separate inflatable floats se cured to the arms, the body, and the legs ol tl' \\'e""r, and being inflatable by a single inila ng pump.

still further object of this invention is to provide a two-part inflatable suit, having watertight connections, and provided with a. helmet, having a visual opening and a breathing valve,

lilith. 'these general objects in view, and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement ot parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

ln the drawings forming a part .of this application and in which like-designating characters reifer to corresponding parts throughout the several views, Figure 'l is a front elevation of the complete device as worn by a person and havingr a part broken away and lshowing` a pump connected with the air-inlet pipe. Fig. 2 is a detail enlarged sectional view taken upon line lI-Il of 1. lli 3 is a transverse sectional view :en upon line lll-lll ot Fig. 1. Fig. Il a sectional view taken upon line lV-V oi.i Fig. Fig. 5 is a sectional view taken upon line ifwV of Fig. l. p lfig. G is a similar view upon line 7l-Vl of Fig. 1. Fig. 7' is sectional view taken upon line VIL- Vl'lot Fig. 1, and, Fig. 8 is an enlarged perspective detail view of the cam securing means between the suit sections.

Referring more in detail to the drawings, the device broadly consists in a suit formed ot a jacket 10, and trousers 11, each being provided with a means for floating' the 'wearer of the suit. The trousers 1l are provided with shoes 12 formed therewith so as to constitute a single waterproof garment while the jacket 1() is provided with gloves 13 formed therewith, and making a single garment and with the helmet llt which is also waterproof, there is formed a complete waterproof covering for the entire upper portion of the body. The jacket l0 is provided with a bottom lange 15 at the waist line of the jacket which has a depending` flange 16 adapted for reception within the groove 17 of the belt flange 18 of the trousers. The jacket flange has a dependent bracket 19 secured thereto for pivoting a cam 20 adapted to engage within an outer bottom groove 21 of the belt flange 18.

The wearer of the life-preserver enters the same by putting on the jacket and trousers and tightening the cam 20 for providing a watertight connection therebetween, and in which condition the wearer may enter the water and remain perfectly dry.

The legs of the trousers 11 are provided with outwardly positioned inflatable cushions 22, connected together' by means of an air pipe while one ofthe cushions 22 is connected to one ol the inflatable side wings 24C. of the jacket l0 by means of the detachable pipe coupling, the details of which are illustrated in Fig. 5.

An air entrance tube 26 is connected to the rear oll one of the side wings 24 and adapted to be inflated by means of any form of air pump, such as 27. The two side wings 24 are in communication by means of a connecting pipe 28. The arms 29 of the jacket are each provided' with oppositely positioned air cushions the members of each pair being connected together by a tube 31. One cushion of each of the pairs of arm cushions are connected to the adjacent side Wing 24 of the jacket by means of a pipe 32. By this arrangement it will be seen that air may be asf roo

forced through the tube 26 by means of the pump 27 into one of the wings 24, and from whence the air passes to the other wing 24, and from each wing to the pairs of arm cushions, Awhile from the side wing 2li which receives the air from the pump, the air passes to the adjacent cushion 22, and then to the companion cushion 22. It will be seen that all ot the cushions are thus inflated by operating the single pump 27 and the air. is retained therein by closing the entrance nipple 33. It will be evident the supply pump .may he attached to the entrance nipple 83 of either of the side wings 24, while two of the cam securing means 20 are referably provided for the suit iianges as illustrated 1n Fig. 4.

,The helmet 14 is provided with a. front glass 34 for allowing the wearer to see through the same, While a breathing tube 35 is positioned adjacent the mouth of the wearer, and is secured to the Jfront side of the helmet. The tube 35 is provided with 'an Opening 36 and has a central bore 37 com- A municating with the interior of the helmet securing the suit in its proper position and having the several cushions thereof inated may readily enter the water and oat and svviin as he desires, and during which time he is able to direct his course and to freely breathe through the helmet vaive while at uii times he is protected from the Water, and' is insured against sinking. I

While the forros of the invention herein uiiy described are preferred, it is understood that chances ma be mede in the de 1,1 rasee ,pending annular rib, a beit iange upon the trousers having a groove in the top thereof adapted to receive the said rib, cam locking means between said ianges, iniataloie cushions positioned upon the arms, legs, and body portion of the device.

2. A life-preserver comprising a jacket, a helmet upon said jacket, an air-breathing valve carried by said helmet, a bottoni flange upon said jacket, depending brackets carried by said tiende, rocking cams pivoted to said brackets, iniiatable cushions carried by the arm portions of said jacket, and infie-table s ide wings carried by said jacket, and having communication vwith said arm cushions, a belt ange adapted to engage said bottoni flange, and in locked relation with said Harige, and ioat mounting means, secured to said belt iiange and .means for iniating said cushions.

in testimony whereof We aiiix our signatures in presence oi two witnesses.
